Square billet heating furnace induction heating coil is a contour design, copper tube is wrapped with T2 oxygen-free copper, copper tube wall thickness ≥2.5mm, furnace body insulation material is selected from the United States imported knotting material, high strength, high temperature resistance, longer service life Long; steel billet secondary heating equipment furnace body inlet and outlet end is sealed with 5mm copper plate, which greatly reduces magnetic leakage and prolongs service life. The frame structure of the furnace body is made of non-magnetic stainless steel or aluminum alloy to reduce the influence of magnetic flux leakage and heat on other devices. Square steel billet induction heating equipment is equipped with one water-cooled idler roller between each two furnaces. Each roller is equipped with a variable frequency speed regulating motor to ensure stable and uniform operation of the billet.
The billet is driven by the motor and the idler at a constant speed in the induction heater. The billet is heated uniformly, the heat loss is less, and the heating efficiency is high. The discharge port is equipped with the American Leitai thermometer to display the billet heating temperature in real time and keep the workpiece. Uniformity. The slab heating furnace is automatically higher than the general equipment, which is convenient for operation and has a high degree of online intelligence for other equipment. The square billet heating furnace is evenly heated. The billet after heat treatment has no cracks, no over-burning, no straightening machine for straightening, tensile strength and toughness, all of which can meet customer needs.
Square billet heating furnace use conditions and user-owned parts:
1 . The user provides the high-voltage side power supply of the transformer, the electrical connection line of the transformer to the low-voltage distribution cabinet and the power supply cabinet, and the console enters the line.
2 . Altitude: ≤ 2000m; Relative humidity: ≤ 90%
3 . Equipment cooling: The total flow of the whole set of equipment is greater than or equal to 200 cubic meters per hour. Pressure ≥ 0.3MPa
4 . No conductive dust and corrosive gases.

What is the square billet heating furnace used for?

Square billet heating furnace is used for induction heating such as billet, billet, round billet, etc. Such equipment generally has other processes behind it, such as heating steel billets and rolling into steel bars and wire rods.

Square billet heating furnace price

The industrial steel billet heating furnace can be divided into cold billet heating furnace and steel billet, continuous casting and online heating furnace according to the customer's process. The power of different equipment is different, and the workpieces to be heated by each customer are different. Therefore, the price of the equipment is not the same. When purchasing a billet heating furnace , you should first locate your own needs and find a larger, professional manufacturer.

How is the square billet heating furnace precisely temperature controlled?

Adopt two-point temperature measurement. In order to ensure the precise control of the temperature of the billet and the continuous casting billet during the heating process, an infrared thermometer is generally arranged at the inlet and the outlet. In addition, in order to make up for the time difference between the temperature measurement of the thermometer and improve the control sensitivity, a hot body detection device is installed at the inlet and the outlet of each group of furnaces, so that the heating furnace can be more sensitive and reliable in maintaining low power and high power switching without material and materials. .

How to choose the square billet heating furnace ?

The traditional steel rolling process is that the steel slabs obtained by steelmaking are cooled by stacking, transported to a rolling mill, and then heated by a heating furnace to be rolled into steel. This process has two drawbacks. First, the billet is pulled out from the steelmaking continuous casting machine and has a temperature of 700-900 ° C on the cold bed . The latent heat of the billet is not effectively utilized. Second, after the slab is heated by the heating furnace, the surface loss of the slab is about 1.5% due to oxidation loss . The steel-making workshop energy-saving and emission reduction technology transformation project implements continuous casting and rolling for the above problems, but the second point defect is still used in the regenerative heating furnace . In order to fully save energy, it is more suitable to use the square billet heating furnace for on-line heating and uniform temperature heating of the continuous casting billet.

The role of square billet heating furnace ?

The billet warming and heating furnace is a continuous casting billet (small billet, slab, round billet, rectangular billet) which is heated by the heating furnace before entering the rolling mill to realize continuous casting and rolling production. The heating capacity of the whole billet is heated to 1100 ° C , and the temperature uniformity is passed through the induction heating furnace to ensure that the temperature uniformity of the billet is better than the natural state before heating.
